Title: Liquid crystal display element
Inventor: TAKATORI KENICHI
IPC: G09F9/35
Filed: 1992-02-20
Abstract: PURPOSE:To obtain a wider angle characteristic having poor dependency on visual angles by providing a plurality of regions varying in the orientation direction of liquid crystals within one picture element and positioning the boundary part within these regions onto such holding capacity line which divides the picture element to a plurality. CONSTITUTION:A liquid crystal material 6 is clamped between two sheets of supporting substrates 5 and the plural regions varying in the orientation directions of the liquid crystals are provided within the one picture element 1 with the holding capacity line 2 as the boundary. Although the directions of the twists are the same in the liquid crystal orientation of the divided region (I)3 and region (II)4, the orientations on the surface of the substrate vary. Further, the parts being called disclination where the orientation of the liquid crystals is discontinuous are generated at the center of the holding capacity line 2 by the structure to position the divided parts 20 of the region on the holding capacity line 2. This holding capacity line 2 is provided by using materials which do not allow the transmission of visible light, i.e., various kinds of metallic materials, such as chromium and aluminum. The inter-region parts where the disturbance in the light transmission by the disclination is generated are thereby prevented from entering the observer's eyes in actual display.

IPC: H02P5/46
Filed: 1979-03-23
Abstract: PURPOSE: To perform both digital-speed control and tension cotrol at the same time, by detecting an actual tension between the sections by a tension detector provided in an appropriate section, comparing said actual tension with a tension reference value, and compensating the speed.  
     CONSTITUTION: A required tension-reference value is input to a computer 51 by a tension-increasing push-button switch 19 and a tension-decreasing push-button  switch 20. Then, the actual-tension value detected by a tension detector 21 is input  to the computer 51 and the difference between the digital value of the actual tension and the previously memorized specified tension value is obtained. The amount of tension compensation is obtained by comparing the difference in tension and the lowest predetermined difference, and said amount is transformed into the amount of speed compensation, and it is used for digital-speed control.

Filed: 1986-02-18
Abstract: PURPOSE:To reduce the area of a chip by providing a switching means which connects an output means to the output node of an address decoder that is fixedly associated with said output means while a switching command signal is outputted. CONSTITUTION:When a low voltage at +5V, for instance, is impressed on an input terminal A12, a level detector 14 outputs a normal read mode signal. As a result the address decoder 12 decodes an address signal supplied from the outside to select a memory cell, reads information in the selected memory cell to an I/O buffer 13, and outputs it to an external device through output terminals O0-O7. Namely, a switching transfer gate 15 connects the buffer 13 to an output terminal group 16. Next, when an input voltage of +12V at a high level is impressed on the terminal A12, the detector 14 outputs the switching command signal. As a result the gate 16 connects each output node of the decoder 12 to the terminal group 16.

IPC: H04L25/08
Filed: 1980-03-21
Abstract: PURPOSE:To reduce the radio interference noise, by using the trapezoidal wave pulse signal in the transmission system using the pulse signal. CONSTITUTION:When a positive-polarity square wave signal is inputted to terminal 1 as signal input A, transistor Q1 is turned on, and next, transistor Q3 is turned on. When a negative-polarity square wave signal is inputted to terminal 2 as signal B simultaneously, transistor Q2 is turned on, and next, transistor Q4 is turned on. At this time, diodes D1 and D2, transistors Q3 and Q4 and resistances R3 and R4 constitute a constant-current circuit to charge capacitor C. Consequently, base potentials of transistors Q5 and Q6 change linearly, and the transmission output becomes a trapezoidal wave where the rise and the fall of the signal input are inclined linearly, and the output signal becomes trapezoidal pulses. As a result, radio interference generated for transmission of the square wave is prevented.
